Upgrade Kamailio from v4.3.x to v4.4.0

The page contains the details about the changes that were made to old components during the development of v4.4.0 compared with what existed in v4.3.x. It does not include the brand new modules, focusing on how to upgrade database and configuration file from v4.3.x to run with Kamailio devel.

Previous Stable Release

If you look for the guidelines to upgrade to previous stable release, see:

Remarks

INF - the change doesn't really have any direct impact - no action required in old config

CPM - the change was used with the new value via explicit parameter in default config file from old releases

RCM - the change is recommended to be done if you had an explicit different or lower value for this parameter in old config

Modules

ims_dialog

The dialog-ng module was renamed to ims_dialog.

The modparams statements in your configuration file must be updated to reflect the new name of the module.

# old version
modparam("dialog-ng", ...)# new version
modparam("ims_dialog", ...)

The functions for routing blocks are the same, no changes are required there.

Core

Parameters

fork

(INF) This is just heads up notification that the fork parameter is planned to be refactored in the next version, because fork=no disables many features without explicit visibility (e.g., no tcp/tls, only listening on first network interface). The value fork=yes will preserve existing behaviour.

Database

There are quite minimal changes to the database structure, in short:

presence active_watchers table has new columns

permissions trusted table has new columns

uac uacreg table has new columns

MySQL Database Structure
